SPECIFICATION forming part of Letters Patent No. 353.432, dated-November 30. 1886. Application flied lITovember 7, 1884. Renewed J une 25, 18H6. Serial No. 206,243: (No model.)

To aZZ whomI it may concern.'

Beit known that I, GUsrAv ADOLF SACHS, of Valley City, in the county of Barnes and Territory of vDakota, have invented certain new and useful Improvements in Breech-Loading Fire-Arms, of which the following is a specification.

This invention has reference to certain improvements in breech-loading fire-arms, and more especially to improvements in breechloading double-barrel Shotguns of that class in which the barrels are fulcruxned to the breech-block and adapted to be thrown into inclined position for inserting new cartridges, after which theyr are returned to and locked to the breech-block; and the invention consists of improvements in the mechanism for locking the barrel or barrels to the breechblock, of an improved device for extracting the shells, and of an improved construction of the actuating mechanisms for the hammers and firing-pins.'

In the accompanying drawings, Figure 1 represents a side elevation of my improved breech-loading fire-arm. Fig. 2 is a vertical longitudinal section of the same, drawn on a larger scale, showing the barrels locked to the breech-block. Figs. 2 and 2b are respectively a detail end view and inside view of the hammer-actuating mechanism; Fig. 3, a side elevation,` partly in vertical longitudinal section, showing the barrel iu inclined position, ready for inserti-ng a new cartridge; Fig. 3, a vertical longitudinal section of the hammeractuating mechanism, with the hammer in raised position; Fig. 3, a detail end view of the extractor. Fig. 4 vis a top view of the fire-arm.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the stock, B the breech-block, and C C the barrels, of my improved double-barreled breech-loadingiirearm. The barrels are fulcrumed by a strong lug, C', intermediately between the barrels, to a recess at the front end of the breech-block B, the tight fitting of the lug C to the fulcrumpin b being secured by a soft-metal bearing, b', that is adjusted by a set-screw, b2, which passes longitudinally through the lug C', as shown clearly in Fig. 2.` f

The barrels C C are provided with a fixed hook, d, near their breech end, which hook enters into a recess, d', of the breech-block and is locked to the same by means of a slide-piece, d, which is guided in the rear part of the breech-block. The rear end of the locking slide-piece d2 is pressed forward by a strong band-spring, da, so as to keep up the reliable interlocking between the hook d and the slidepiece d. The rear end of the locking slidepiece d2' is slotted and a lever, D, passed through the said slot, the lever being ful, crumed at its upper end to lugs d* of the tailpiece B of the breech-block B, and extended through the bottom plate, B, of the hammeractuating mechanisms to the outside, as shown in Fig. 2. The outer end of thelever D is located in front. of the triggers, within the guard-piece of the same, as shown clearly in Figs. 1, 2, and 3.

By pulling back the lever D the locking slide-piece d2 is released from the hook d, so that the barrels can be thrown on their fulcrum into inclined position, in which position the shells are removed and new cartridges inserted. l

The extractor E, that serves for both barrels, is located at the breech end of the barrels, and provided with a slotted forward-extending shank, E', at right angles to the extractor E.

The segmental edges of the extractor E are rey cessed for engaging the rims of the cartridgeshells, as shown in Fig. 3. The shank E of` the extractor E is guided by slots on the hook d, the stop-screw e, and the lug C, as shown clearly in Fig. 2. The frontend of the extractorshank E is rounded o and engaged by upwardly-curved toes e of the breech-block B, so that when the barrels C C are thrown into inclined position the pressure of the toes e on the shank E moves the extractor back. ward and withdraws the shells from the breech of the barrels. The lower edge of the extractor E is rounded off, so as to pass readily along the rear part of the breech-block, which latter pushes the extractor forward into its normal position, while -the barrels are returned into locked position. The upper end of the extractor E is centrally perforated and guided along a fixed longitudinal pin, e2, that extends from the solid portion intermediately between the barrels C C to a rearwardly-extending lug, e3, of-the same, said guide-pin and lug itting into a recess, e, at the top part of the breech-block, as shown in Figs. 2 and 4. By

this arrangement the extracto/r E is steadily 'guided while movingin forward and backward position and the shells extractdfar enough to be quickly removed 4on settin'gqthe barrels into inclined position.

The tail-piece B of the breech-block B is connected by a strong center stay, B, to the bottom plate, B3, and firmly bolted to the latter. The center stay, Bz, separates the ham meractuating mechanisms, which .are located at each side of the same.

' The hammers F are fulcrumed to the side plates, F', of the hammer-actuating mechan isms, each being actuated in the usual manner by a strong niainspring, F2, when the trigger- G is pulled. The trigger G releases the fulcrumed triggerlever G' from the notches of the hammer-shank. Thecurved front part of` the hammer F strikes against anenlarged cupshaped portion, f', at the upper end of a safety guard spring, f. The cup-shaped upper portion, f', strikes against the head of a springcushioned firing-pin, f2, and moves the same forward, so as to ignite the priming of the cartridge. The shank and head of the firing-pin f2 are guided in a perforation of the breechblock in line with the axis of the barrel. As soon as the hammer is raised the firing-pin f is thrown back by its spring also the cupshaped portion of the guard f which is arranged for protecting the heads of the firingpin fz against the blows pf the hammer. The lower end of the spring-guard f is attached to the rear part of the breech-block, as shown- 'in Figs. 2, 3, and 3*.

The side plates, F', of the hammer-actuating mechanism are connected by transverse screw-bolts and rigidly secured to the recessed sides of the tail-piece B of the breech-block, as shown in Fig. 4. A projecting lug, g, at the front of each side plate, F', enters into a recess, g', at each side of the breech-block, so as to form a steady and reliable connection therewith. To each side plate, F', is applied a hammer, a hammer-actuating mainspring, atrgger, and a trigger-lever, which are retained by an interior auxiliary plate, F3. On detaching the side plate, F', from the tailpiece of the breech-block and Astock A the parts mentioned are detached therewith and can be conveniently inspected and repaired, as shown in Figs. 2 and 2".

The hammer-actuating mainspri ng F2 slides by its-upper end, having a pivoted anti-friction block, h, along a projecting heel, h', at the rear part of the hammer F, as shown clearly in Figs. 3 and 3, ywhile the lower end rests on a fixed transverse bolt, h2, that connects the side plate, F', and inner Vauxiliary plate, F. The inner ends of the bolt ha and of the fulcra of the hammer F and trigger-lever G' are threaded for applying screw-nutsl h3, which retain the auxiliary plate F3 in posi tion. The screw-nuts hs are securely held in position by a notched locking-plate, F, as shown in Figs. 2 and 2", which abuts against the stay B1 when the side plate, F', is in position on the tail of the breechblock B. The locking-plate F prevents the unscrewing of the screw-nuts and the getting loose of the parts constituting the ham mer-actuating mechanisms by the concussions to which they are exposed.

The trigger-lever G is acted upon by a V- shaped band-spring, z', that is placed around affixed transverse pin, i', extending from the pla-te F to the auxiliary plate F3, one end of the spring pressing against the trigger-lever, while the other end presses against a second cross pin, i2, as shown clearly in Figs. 3 and 3*.

The triggers G are pivoted to sidewise-projecting lugs m of the trigger-levers, so as to facilitate their convenient passage through the recess of the bottom plate when the dierent parts of the hammer-actuating mechanism are put together.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. The combination of a breech-block, B, having a recessed front end, with toes e' and a top recess, e, fulcrumed barrels C C, having a longitudinal guide-pin, e2, and lug e3 at the breech end, a sliding extractor, E, guided along the pin e, and a slottedshank,E', guided along the under side of the barrels, substantially as set forth.

2. The combination of a breech-block, B, having recessed tail-piece B', a central stay, B2, bottom plate, B, side plates, F', hammers F, extending through the recesses in said tailpiece, and mechanisms for actuating the hammers, supported on the side plates atboth sides of the center stay, substantially as set forth.

'3. In a breech-loading fire-arm, the combination of the hammer F, mainspring F2, side plates, F', auxiliary plate F3, fulcrumed and spring-actuated trigger-lever G', and a trigger, G, pivoted to a laterally-projecting lug of the trigger-lever, substantially asset forth.

' 4. In a breech-loading firearm, the combi' nation of the hammer F, side plate, F', mainspring F, auxiliary plate F, fulcrumed and spring-actuated trigger-lever G', trigger G, pivoted to said lever, transverse screw-bolts having nuts h3, and nut-locking plate F, substantially as set forth.

5. vThe combination of the hammer F, the spring-'cushioned firing-pin f2, having an enlarged/head, and the spring-guard j', having a cup-shaped head, f', normally resting upon said enlarged head, said guard being adapted 1.o receive the percussion of the hammer and impart it to the firing-pin, substantially as described.

In testimony that I claim the foregoing as my IOO invention I have signed my name in presence Witnesses:
